Other Parts Discussed in Thread: LM3670
Usually I create my own symbols and footprints but decided to take Ultra Librarian for a "spin" to target Altium schematic symbols and PCB footprints. I noticed that the GND pin is correctly assigned to a pin with the "power" property. However, the VCC pin (VIN) and VOUT pins were assigned as inputs and outputs respectively. The recommendation from Altium documentation is to make these pins as "power" as well.
The common thread is to throw out the schematic symbol - primarily for pin organization reasons. I haven't been able to find a thread which points out the pin properties for power pins. Although I've only piloted one part thus far - the concern is if I expand this to generate more symbols - they would all share a common issue (per my pin property conventions). This is workable, but adds another touch-up step.
Are regulator VCC pins as inputs and power supply pins (VOUT) as outputs come from a requirement of the Webench plugin? It would be interesting to learn why the pin properties were chosen in conflict with current Altium guidelines.
